LUBBICATOB FOR VEHICLE SPRINGS.

ofIllinois, have invented a new and useful Lubricator for Vehicle-Springs, of which the following is a specification.

. My invention relates to a new and im-- proved device designed to be applied 'to vehicle-springs, more especially to those employed in automobiles, for the purpose of conveniently and thoroughly lubricating between the leaves thereof.

L The objects and advantages of the invention, 7 together with the novel features thereof, will hereinafter appear and be particularly pointed .out in the appended claims.

Referring to the drawing:

Figure 1 is a top plan view of a vehiclespring employed in an automobile, with" parts broken away, and provided with my improvement;

Fig. 2 is a vertical longitudinal sectional view of the same;

Fig. 3 are views in section and bottom plan respectively of. a nut hereinafter referred to; v

Fig.' 4 is a horizontal. sectional view through the center bolt connecting the spring-leaves, a fragmentary view of one of the leaves being shown in connection therewith; I

Fig. 5 is a similar view showing a modified arrangement and form of bolt.

Similar numerals of reference indicate similar parts in all the figures of the draw- For the purpose of illustrating the applicability of my improved spring lubricator device or attachment, I have shown the same in connection with the usual form of channeled axle 1, the same having'a't suitable oints widened portions 2, forming seats or the springs 3.

The upper side or surface of each of the leaves 4, composing the spring, with the exception of the uppermost leaf, may be provided with a longitudinally disposed shallow lubricating groove 5 (see- Flgs. 1 and 2).

The several leaves composin the s ring] lt-ho es 6,

are provided with coincident as 1s usual, for the accommodation of the connecting-bolt 7.

I Application filed March 30,1916. Serial No. 87,837.

For purposes hereinafter apparent, it is desirable that the holes 6 and the bolt 7 be at variance in cross-section; that is to say, if the bolt-hole is circular, (as shown in Figs. 2'a'nd 4), the bolt should be polygonal-preferably rectangular in cross-secand the hole 6,, a plurality of transverse lubricating ducts, which, as.will beapparent, are disposed transversely to and communicate with the grooves 5 heretofore mentioned.

.These ducts I have indicated as 8.

I This form of bolt, it will be understood. is substituted for the usually employed tiebolt. In this instance also the bolt is inserted reversely to what isusual-that is, head down, leaving the nut 9 to be applied -at the upper instead of the lower end of the bolt. Moreover the nut is of peculiar construction, the idea being to provide the nut with orifices leading to the aforesaid transverse ducts 8. To accomplish this the nut may be variously formed but I prefer to provide in the underside of the nut an annular groove 10, and one or more communicating radial grooves 11.(see details Fig. 3).

Any desired means may be employed for containing the lubricant and feeding it to the ducts 9, but I prefer, for convenience of storage and operation, to form a lubricant reservoir in connection with the usually and necessarily employed clip-saddle.

In the present instance the clip-saddle 12 is provided in its underside with a cavity or chamber 13 designed to' contain the lubricant. An opening 14'may be formed in one wall of the saddle and connected therewith may be an ordinary compression grease-cup 15, from which, as'will be seen, greasemay be fed into the reservoir 13, and from thence through the orifices of the nut to the transverse ducts 8 and to the grooves 5 of the leaves thus being spread laterally between the rubbing-surfaces of the leaves."

At each side or near each end of the clipsaddle, seats 16 are formed for the accommodation of the usual clips 17, the terminals plication (filed Dec. 2, 1915 Serial Number 64,631.) I Having described my invention, what I claim, is:

1. The combination with the leaves of a vehicle-spring, provided with alining trans- Verse holes, and intermediate lubricant-conductors for the leaves, of a transverse bolt located in the holes of the leaves for connecting the latter, said bolt being atvarianc'e in cross-section with said holes and combining with the walls of the same to form transverse lubricating-ducts leading to the intermediate lubricant-conductors, a clip-saddle mounted on the leaves and having its underside formed with a lubricant-reservoir receiving the upper end of the bolt and communicating with the lubricating-ducts thereof, and inverted U-shaped clips mounted on the saddle and embracing said leaves.

2. The combination with the leaves of a vehicle-spring, provided with a transverse hole and with longitudinal lubricating grooves in their upper faces, of a bolt located in the holes'of the leaves and at variance in cross-section with the holes, wherebyto provide lubricating ducts communicatlng with the grooves, a clip-saddle mounted on the leaves and provided in its underside with a lubricant reservoir receiving the upper end of the bolt, clips mounted on the saddle and embracing the leaves, and a perforated nut on the upper end of the bolt.

3. The combination with the leaves of a vehicle-spring, provided with a transverse hole and with longitudinal lubricating grooves in their upper faces, of a bolt locatedin the holes of the leaves and at variance in cross-section with the holes, whereby to pro-e vide lubricating ducts communlcating with the grooves, a clip-saddle mounted on the leaves and provided in 1ts underside with a lubricant reservoir receiving the upper end of the bolt, clips mounted on the saddle and embracing the leaves and a nut mounted on JOHN EMIL ANDERSON.
